RESUSCITATOR Filed May 17, 1961 INVENTOR. DALE O. DICK ATTORNEY UnitedStates Patent Ofilice 3,070,089 Patented Dec. 25, 1962 3,070,089RESUSCITATOR Dale 0. Dick, P.0. Box 133, Kinsman, Ohio Filed May 17,1961, Ser. No. 110,680 3 Claims. (Cl. 128-29) This invention relates toa resuscitator and more particularly to a resuscitator by whichartificial respiration may be conveniently and easily given.

The principal object of the invention is the provision of a resuscitatorarranged to be engaged in a persons mouth so as to displace the tonguefrom its normal position and thereby provide a passageway for air movedby the resuscitator.

A further object of the invention is the provision of a resuscitatorarranged to improve the so-called mouthto-mouth technique of artificialrespiration.

A still further object of the invention is the provision of a simple,inexpensive, easily-used resuscitator that will Work efficien-tly inmoving air into a persons lungs as in the case of artificialrespiration.

The resuscitator disclosed herein comprises an improvement in the artrelating to such devices in that a simple and inexpensive device isprovided which may be readily positioned in the mouth of a personrequiring artificial respiration and manually operated to force air intothe persons lungs. The persons nose is held shut so as to prevent theair from escaping until time for the air to be expelled from the pensonslungs and replaced again in the next cycle. The device provides a filterto insure the delivery of clean air to the persons lungs and it enablesthe technique of mouth-to-mout h respiration to be employed Without theactual mouth-to-mouth contact heretofore believed necessary by theperson rendering the artificial respiration and the person receiving it.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being the intention to cover all changes andmodifications of the example of the invention herein chosen for purposesof the disclosure, which do not constitute departures from the spiritand scope of the invention.

The invention is illustrated in the accompanying drawing, wherein:

FIGURE 1 is a perspective view of the resuscitator formed in accordancewith the invention.

FIGURE 2 is a vertical section on line 2-2 of FIG URE 1.

By referring to the drawings, it will be seen that the resuscitatorcomprises an angular elongated tube having an enlarged extension 11which is internally threaded as 'at 12 and arranged to receive anexternally threaded neck 13 on one side of a resilient bulb 14. Theother side of the resilient bulb 14 is secured to a collar 15 which isinternally threaded as at 16 and which in turn receives a threadedtubular end 17 of a circular filter case 18, one side of which is openedand provided with a screen 19. Filter media such as known in the art isprovided in the form of a removable replaceable cartnidge 20 positionedin the filter case 18.

The interior of the enlarged end portion -11 forms an annular shoulder21 against which a flap valve unit comprising an apertured disc 22 and avalve member 23 pivotal'ly secured therto is positioned. The flap valveunit is secured in position by the engagement of the exteriorly threadedneck .13. The collar 15 also forms an annular shoulder 24 and a flapvalve unit exactly like that just described and including an apertureddisc 25 and a valve member 26 pivoted thereto is positionedagainst theannular shoulder 24 and retained in that position by the engagementthereagainst of the threaded tubular end 17 of the filter case 18. V I vIt will thus be seen that when the resuscitator is positioned with thetube 10 in the mouth of the person to which arificial respiration is tobe supplied, the same will reach downwardly into the throat of theperson and displace the tongue in so doing. Manual manipulation of theresilient bulb 14 will cause air to move through the filter cartridgeZii, the valve member 26 and into the bulb 14. Continued manualmanipulation of the bulb 14 will cause the air within the bulb 14 toclose the valve member 26 and move past the valve member 23 into thetube 10 and thence into the lungs of the person. It will thus be seenthat a number of squeezing manipulations of the bulb 14 will cause aquantity of air to flow into the lungs of the person to Whom artificialrespiration is being supplied and that when the lungs have become filledthe device can be moved and the air will flow outwardly of the lungs.The device is then repositioned in the persons mouth and the cyclerepeated as long as the artificial respiration is necessary.

It will thus be seen that the resuscitator disclosed herein meets theseveral objects of the invention, and having thus described myinvention, What I claim is:

1. A resuscitator comprising an elongated angular tube open on one endand having an enlarged internally threaded extension on the other end, aresilient bu-l-b having a neck portion engaged in said internallythreaded extension, a flap valve disposed in said internally threadedextension and arranged to pass air from said bulb to said tube, a collaron said bulb and a flap valve in said collar arranged to pass air intosaid bulb, a filter case having an externally threaded tubular memberengaged in said collar and acting to retain said flap valve therein, afilter in said filter case.

2. The resuscitator as set forth in claim 1 and wherein each of saidflap valves comprises an apertured disc having a valve member hingedlysecured thereto for engagement with one side thereof.

3. A resuscitator comprising a deformable flexible air containing bulbhaving a neck on one side thereof and a collar on the other sidethereof, an elongated angular tube secured to said neck and a first flapvalve mounted between said neck and said elongated angular tube andarranged to prevent air from entering said bulb theret-hrough and topass air from said bulb into said elongated angular tube, a filter casehaving a filter cartridge therein, a tubular extension on said filtercase engaged in said collar, a second flap valve arrangement positionedin said collar and between a portion thereof and said tubular extensionof said filter case, said secondary fiap valve arranged to pass air fromsaid filter into said bulb and to prevent air in said bulb from passinginto said filter.
